To THE LAKE ERIE v or oHIo CHEMICAL COMPANY, F CLEVELAND, OHIO, A CORPORATION VAULT-WALL-PROTECTING ,DEVICE 'Application mammary 31, ieee. serial No. 616,175.

This invention has for a principal object the provision of a protective device for preventing access to the interior of a vault cr other depository in the event that the Walls are attacked to gain entrance, which novv is one of the methodsby whichk burglars force entrance to perpetrato thefts. As a means of accomplishing this result,the invention contemplatesthe employment of a gas discharging device adapted to operate when the Walls of the vault are attacked, to disseminate noxious gas on the interior of the vault and p revent access thereto, even though an opening inthe Wall may be made. c v

Itis also a purpose of the invention to provide a protectingdevice of thistype'whicli Will be of extremely sensitive character and adapted to operate regardless of the position of attack, or the force employed. e

Other objects and advantages of the invention Will be apparent as it is better understoody from the following description, which, taken in connection With the accompanying drawings, discloses a preferred embodiment 25 thereof. y y

Referring tothe drawings,

f Figure 1 is aninterior'perspective view of a portion of a vault in which a protecting system embodying my invention is installed;

.Fig 2 is an elevational view of a portion of the outer Wall of the vault, showing the means by which the lforce of attack is utilized to loperate the gas discharging device;

`Fig. 3 is a transverse section taken substan- 3vin Fig. 2;' y

rFig. 4L is an enlarged vertical section, taken tl rough the bomb receptacle and bolt sleeve;

Fig. '5 is a detailed view, partially in seotion, of the bolt releasing mechanism; and

.40 Fig. 6 is `a tcp plan view of the parts shown in Fig.

Upon the drawings, the main Wall of thek vault is indicated by the reference character -l1 and the character 12 indicates an inner -15 Wall .which is spaced from the main wall by suitable spacing members 13 and 141.

,A box, or casing, 15 is positioned on the interior of the Wall part 12 and contains a gas receptacle 16, which preferably is of glass, or

' other material-.adapted to be easily broken.

When the slideis inproper position.

As shown, the gasreceptacle is of segmental form and 'a ball 17 is positioned'betvveen the segmentsand in postion tobe struck by a plunger 18 When the latter is projected by a spring 19. Said plunger is normally held retracted and under the tension of the spring 19 by means of a flexible connection 21, secured to the upper end'of aneXtension rod 22 upon which said spring is mounted. Said plunger and spring are enclosed in a sleeve 23, ywhich has lupper shoulders 24 against Which the spring engages. A slide 25 is provided in the top of theboX 15 and has an aperture throughjwhichthe plunger 18 mayexend aid slide is provided also' With slots 26 through which guiding screws 27 extend and it Will be manifest that when said slide is in its outer postion,`the system Will be rendere'dinoperative, since vthe plunger Will'be prevented from breaking the receptacle.' `The connection 21 extends over a sheave which is positioned in a block 28 and is connected at its opposite end to a rod-29 which is housed in a sleeve 31. Said sleeve has one end secured in a block 32, which is apertured to permit the rod 29 to move therethrough. Said rod is provided With a cut-out 33 adapted to be engaged by an arm 34 of a lever 35, said arm being normaly held in engagement With the rod'by means of a spring 36 which is positioned in the block 32.'` Said lever is adapted to be operated to disengage the rod 29 by means of a'trip lever 37, which is mounted for actuating the lever 35,`an arm of which extends through the Wall part 12. Said lever 37 is operablepby means to be now described.

Said trip lever 37 is operated by aconneetion 38, which extends about a sheave 39 and is se` cured to a ring 11. Said ringv is connected by means of a plurality of Wires, or other flexible connections, 4t2 with the opposite ends of'yokes 13, the latter-'being of whiiiletree type, being pivoted'at a central point 411 to a plate extending out from the Wall spacing member 13. A Saidyokes, or Whiffletrees, 113 are operated by means of a plurality of Wires, or cords, arranged at close intervals -about the Walls of the Vault to .Operate vthe trip leve'r37.

It will benoted that these connections are arranged in the iioor and ceiling, as well as on the side walls and they may be briefly traced as follows. AReferring to Fig. 2, it will be seen that a connection 46 is secured at 47 to one oi the yokes and extends around Y sheaves Ll'at the bottom of the wallE and similar sheaves 419 at .the top, l eing directed up and down at relatively close intervals in this manner.' Another connection 5l is connected' 'at 52' to another yoke i3 and extends about sheaves 53 and 5% whereby it is directed over the area of the plate Ll5 and thence over a' nection 5l'extendstherethrough and. aroun l.

suitable rollers, or guides, 57 at the ends .of saidmembers.

Another connection'v 58 is secured at 59A to one of the members'llf andiextendsdown about a sheave` 6l and is directedover the floorv through channel members 62, correspending tothe members 56 on theV ceiling. A fourth connection 63 is secured ateitoa fourth' member '43- a'nd it extends about sheaves 65, and 67 to the side wall, shown at the leftin Fig'. 2, and it will be under.- stood that theseconnection's may be extended', as des1red`,-'to vcover'any wall arrangement.V

Springs 68Lare providedior each. oi: the mehr, bers' 43, being connected thereto atthe end opposite that -to which the wires Y aref eon nectedv and-having their opposite ends `v`secured as atV 69 to the plate 45; It will thusbe evident that if one of the wall protecting' connections is pulled or stretched byv an attack on the wall, the side of the whiietr'ee43v to which'it is attachedwill be drawn downA andthe ring 41 moved therewith, thus operatiugVv the lever 37 vand permitting the: spring 19 to project the plunger 18 tov discharge the gas.` If, on the other hand,=tlieconnection be broken, one oi' the springs 68 will pull the opposite end'of the member 43' downwardly with similar result. Thusran attack at any point, either inY the' wall, the ceili-ng, or the iioor will result in a discharge of noxious gas into the interior ofthe-vault, rendering the same inaccessible and the burglar will be foiled,` even though his attack may have: resulted in providing an opening through which he might otherwise enter.

It isV thought that the invention and many ot its attendant;- advantages will be understood from the foregoing description, and it will beafpparentv that various :changes may be made in the form, construction and arrangement Vof' the parts.' withoutl departing from the spirit and scope 'of the invention', or sacriticing allv of: its material advantages, they form hereinbe:llore described* being; mere'- ly a preferred embodiment thereof.
